Application filed July 17, 1909. Serial No. 508,194.

To all whom it may concern:

Be it known that I, JAMES L. Sownnn, a

A further object of my invention is to provide an attractiveprophylactic drinking vessel, especially adapted for use at sodafountains and other public dispensaries of beverages.

A further object of my invention is to provide an inexpensive and strongform of aseptic drinking vessel, which will combine a maximum ofstiflness with a minimum of weight.

In the accompanying drawings, forming a part of this application and inwhich similar reference numerals indicate corresponding parts in theseveral views: Figure 1 is a perspective view, illustrating oneembodiment of my invention; Fig. 2 is a section on the line 22 of Fig.1; Fig. 3 is a section on the line 3-3 of Fig. 1; Fig. l is a blank forforming the bottom and stiffening reinforcements shown in the precedingfigures; Fig. 5 is a perspective view, illustrating a modifiedconstruction, and Fig. 6 is a section on the line 66 of Fig. 5.

Referring especially to Figs. 1-il of the drawings, 1 indicates thewalls of a drinking vessel, or tumbler, which are formed of a band ofparaflined paper, or other thin impervious material, having its endsconnected by a preferably overlapped joint 2 to provide a smoothinterior surface. A bottom 3, of similar material, is formed from ablank provided with a marginal portion l, for overlapping the lower edgeof the band 1 and provided with a plurality of pointed tabs 5 and 6 ofdifferent lengths extending alternately in a continuous series from saidmargin for attachment along the outer surface of said band. By thusarranging alternately about the bottom two sets of tabs 5 ando ofdifferentlengths, I produce a. progressively decreasing stiffness, fromthe bottom through that portion of the flexible band 3 which isreinforced by both sets of pointed tabs, and a less rapidly decreasingstiffness from said portion throughout that portion reinforced by thelonger'set of tabs alone.

The pointed tabs 5 and 6 are shown extending, respectively, throughsubstantially one-sixth and one-third the height of the flexible sidewalls 1; thereby reinforcing said walls to provide a maximum stiffnessat the bottom, and a progressively decreasing stiffening throughout thelower third of said flexible walls. It will be noted that at the pointedends of the longer tabs 6 the Stiffness gradually merges into that ofthe unreinforced flexible side walls, thus avoiding any sharp line ofdemarcation which would constitute a weak section tending to distor tionin use.

From the above description, it will be understood that my inventionprovides an improved construction, in which the margin 4 willsecurely'seal the vessel, and the pointed tabs 5 and 6 will provideconvenient means for very securely attaching the bottom in position andreinforcing the side walls to provide a maximum of stiffness with aminimum of weight.

The drinking vessel is shown tapering to permit compact nesting of aseries thereof, and can be inexpensively manufactured by the employmentof a tapered mandrel and former.

Figs. 5 and 6 illustrate a modification, in which the drinking vessel isformed with cylindrical flexible side walls 7 having a bottom attachedin the previously described manner, and corrugated at 8 throughout theirlower portion; said corrugations acting to stiffen the relatively thinside walls for a distance above the reinforcing pointed tabs, and toaugment the attractiveness of the vessel. This modification can beconveniently manufactured in an inexpensive manner by employing acylindrical corrugated mandrel and a corresponding corrugated former.

I have illustrated and described preferred and satisfactoryconstructions, but changes could be made within the spirit and scope ofmy invention.

Having thus described my invention, what I claim as new and desire tosecure by Letdifferent lengths arranged alternately in a ters-Patent is:

1. A drinking vessel comprising flexible side walls formed of uniformstiffness throughout, and a bottom having pointed tabs of differentlengths arranged alternately about its periphery and attached along saidside walls, whereby said side walls will be reinforced to produce amaximum stiffness adjacent said bottom and a portion of progressivelydecreasing stiffness extending therefrom, substantially as described.

2. A drinking vessel comprising side walls formed of a flexible band ofuniform stifiness throughout, and a bottom provided on its peripherywith two sets of pointed tabs of continuous series and attached alongthe outer surface of said band, thereby providing a progressivelydecreasing stiffness from the bottom through the portion of the flexibleband reinforced by both sets of tabs, and a more gradually decreasingstiffness from said portion throughout the reinforcement of the longerset of pointed tabs alone, substantially as described. I

In testimony whereof I afiix my signature in presence of two witnesses.
